JBO Thread Plug Gauge – UNEF Go-No/Go, Right Hand, 2B, 1/4 x 32 is a precision inspection tool designed to verify threaded holes against the UNEF standard. It is essential for manufacturers, automotive shops, and aerospace suppliers who need quick, reliable checks of hole threads to ensure proper fit and function.

With its go/no-go design and right-hand thread specification, this gauge lets operators quickly distinguish conforming from non-conforming threads, helping control quality and reduce rework in high-demand production environments.

• Fast go/no-go checks: Quickly determine whether a hole meets UNEF 1/4 x 32 right-hand specifications, shortening inspection time and speeding throughput.
• Precise UNEF 1/4 x 32, 2B tolerance: Matches the exact thread form and class, delivering repeatable accept/reject criteria for consistent part quality.
• Durable, user-friendly construction: Built for daily shop use with a comfortable, secure grip and robust ends for long life and easy handling—even with gloves.

Using this gauge helps you verify threads accurately during assembly and maintenance, reduces guesswork, and ensures parts will thread smoothly with the intended fasteners. It supports faster inspection cycles, improves first-pass acceptance, and contributes to reliable performance across serial production, repair, and overhaul workflows.
